CHURN-POWER.

$PECIFIGATION forming part of Letters Patent No. 639,712, dated December26, 1899.

Application filed March 1 8, l8 9 9.

To all whom it may concern:

Be it known that I, JOHN T. COLEMAN, a citizen of the United States,residing at Mic cosukee, in the county of Leon and State of Florida,have invented a new and useful Churn-Power, of which the following is aspecification.

The invention relates to improvements in churn-powers. r

The object of the present invention is to improve the construction ofchurn-powers and to provide a simple and comparatively inexpensive onewhich will be capable of rapidly efiecting the production of butter andin whichthe gearing will be housed, but which will affordready access tothe same. The invention consists in the construction and novelcombination and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended.

In the drawings, Figure 1 is a perspective view of a churn-powerconstructed in accordance with this invention, the casing being partlyswung back and the churn-body being removed to illustrate theconstruction more clearly. Fig. 2 is aside elevation of the same, thecasing being in position. Fig. 3 is a vertical longitudinal sectionalview. Fig. 4 is a transverse sectional view on line 4 4 of Fig. 3. Fig.5 is a similar view on line 5 5 of Fig. 3. Fig. 6 is a detailperspective View of the front end of the top of the casing, illustratingthe manner of locking the latter in position.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a supporting-frame composed of two sides 2, rising from anextension of a rectangular base 3, and these sides, which aresubstantially L-shaped, as shown, are connected by transverse rods 5'and have open upper portions provided with cross bars 6 and 7 to formbearings for the gearing and to provide supports for the transverse rod,which is located near the center of the supportingframe. The power isderived from a barrelspring 8, arranged within the frame and connectedwith the same and with a windingshaft 9, having one end squared andextend- $erial No. 709,632. (No model.)

The winding-shaft or drive-shaft is connected by a suitable clutch witha drive-wheel 11, which meshes with a cog-wheel 12 of a counter-shaft13, which is connected with a horizontal shaft 14 by sprocket-gearing. Asprocket-wheel 15 is mounted on the shaft 13 and receives asprocket-chain, which extends to a sprocket-pinion 17 of the shaft 14,and the latter is connected with a front horizontal shaft 18 bysprocket-gearing, consisting of ahorizontal sprocket-chain 19 andsprocketwheels 20 and 21, mounted, respectively, on the shafts 14 and18. Instead of employing spur-gearing for connecting the shafts 9 and 13the drive-wheel 11 and the cog-wheel 12 may be omitted and thesprocket-wheel 15 will thenbe mounted on the winding-shaft 9.

The front horizontal shaft 18 has keyed or otherwise secured to one ofits ends a wheel or pulley 23, having an eccentrically-arrangedWrist-pin 24 to receive a pitman 25 and provided with a groovedperiphery 26, adapted for the reception of a belt, so that the motor canbe connected with a sewing-machine or the like. The pitman is connectedat its lower end with a vertically-reciprocating rod 7 tachably securedto it by means of a cuff or other suitable device. The dasher-rod 32,which reciprocates through an opening of the top of a churn-body 33, isprovided at its lower end with a fixed dasher 34, and it has a rotarydasher 35 journaled on it and arranged above the fixed dasher, and thesedashers are adapted to thoroughly agitate the contents of the churn-bodyand are capable of rapidly efiecting the production of'butter.

The churn-body, which preferably consists of a cylindricalreceptacle,may be of any desired construction and is retained on the base byadjustable clamps 36, having curved flanges to engage the churn-body andprovided with slotted arms or plates 37, receiving adjusting devices 38,consisting of screws or bolts passing through the slots and mounted onthe base and adapted to retain the clamps at any desired adjustment.

The cover of the churn-bod y is detachably held in place by anadjustable rod 39, having its lower end bent at right angles to form afoot and bifurcated to straddle the dasherrod, and this foot 40 engagesthe cover and is held in such engagement by a clamping de vice 41, whichconnects the upper end of the bar with the arm of the frame. The bar,which is arranged vertically, is provided at its upper end with a slot42, and the clamping device consists, preferably, of a screw and loweredand which is secured at the desired elevation by a set-screw.

The speed of the churn-power is controlled by a brake consisting of abrake-wheel 48, mounted on the shaft 18, and a resilient bar or shoe 49,secured at one end to the supporting-frame and engaging the brake-wheelat a point between its ends. The free end of the bar or shoe is engagedby a rotary cam or eccentric 50, mounted on a spindle or stem 51, whichis provided with an eXteriorly-arranged handle portion and which isadapted to be rotated to vary the pressure of the bar .or shoe on thebrake-wheel.

The supporting-frame and the gearing are housed within an L-shapedcasing 52, con.- sisting of two L-shaped sides connected at the back andtop by a continuous strip and provided with a hinged front 53. The L-shaped casing is hinged at its lower end at 5 1 to the back of thesupporting-frame and is adapted when the hinged front is opened to beswung backward, as illustrated in Fig. 1 of the accompanying drawings,to expose the gearing and the supporting-frame. The back of the casingis provided at the bottom with an eye, which is arranged between a pairof eyes of the extension of the base, and the pintle of the hinge 54passes through the said eyes.

The front 53 has its upper end 55 hinged to. the top of the casing, andit is provided at opposite sides with flanges and is secured in itsclosed position, as illustrated in Fig. 6 of the accompanying drawings,by a fastening device 56, consisting of a hook hinged to the easing atone side thereof and engaging an eye 57 of the adjacent side of thefront. The hook is adapted to be readily sprung into and out ofengagement with the eye 57, and it looks the casing in its closedposition. The side of the casing adjacent to the pitman and the wheel orpulley 23 is cut away, and a slot 58 is provided for the projecting endof the windin g-shaft.

The invention has the following advantages: The motor, which is simpleand comparatively inexpensive in construction, is strong and durable andpositive and reliable in operation, and while it is especially adaptedfor churning it may also be used for other light work. The casing, whichhouses the supporting-frame and gearing, is hinged at its lower end atthe back of thesupportingframe and is adapted to be swung rearward touncover the same, and the fastening device of the hinged front locks thecasing in its closed position.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacrificin g any of the advantagesof this invention.

What is claimed is- 1. In a device of the class described, the
